[Bug 985341] Re: segfault when starting rrdcached

[Bryan Quigley]

** Description changed:

- [Workaround]
+ [Impact]
  
- Create /var/lib/rrdcached/journal, then restart the daemon
+  * rrdcached doesn't start by default due to directories not being there
  
- [Original Description]
+ [Test Case]
+ 
+  * Just install rrdcached and see that it doesn't start.
  
  # apt-get install rrdcached
  ...snip...
  Setting up rrdcached (1.4.7-1) ...
  Starting RRDtool data caching daemon: rrdcached/etc/init.d/rrdcached: line 57: 19826 Segmentation fault      (core dumped) start-stop-daemon --start --quiet --oknodo --pidfile "$PIDFILE" --exec $DAEMON -- $OPTS -p "$PIDFILE"
  invoke-rc.d: initscript rrdcached, action "start" failed.
  dpkg: error processing rrdcached (--configure):
-  subprocess installed post-installation script returned error exit status 139
+  subprocess installed post-installation script returned error exit status 139
  Errors were encountered while processing:
-  rrdcached
+  rrdcached
  E: Sub-process /usr/bin/dpkg returned an error code (1)
+ 
+ [Regression Potential]
+ 
+ The change is just adding mkdir -p to two directories in the init script
+ before trying to start the daemon.
+ 
+ I can't think of an obvious regression here.  Takes (incredibly
+ slightly) longer to start?
+ 
+ [Workaround]
+ 
+ Create /var/lib/rrdcached/journal, then restart the daemon
